Coronary Sinus Function  

In the heart, a coronary sinus is an aggregation of veins that have been joined together to form a large blood vessel. It collects blood from the myocardium or the wall of the heart. It is present in the right atrium and is sheltered by the coronary valve. The coronary valve is a part of the lining membrane of the auricle, which is semicircular in shape. The coronary sinus has an opening called coronary sinus orifice. It is also known as the ostium of the coronary sinus. It is protected by the Thesbian valve.

The coronary sinus receives blood from different parts of the heart such as the left marginal vein, the left posterior ventricular vein, and the small, middle and oblique cardiac veins. The coronary sinus drains this blood into the right atrium into the inferior vena cava opening.

Rarely, there may be patients suffering from a coronary sinus atrial septal defect or ASDs. When this disease is not diagnosed and hence, not treated, it tends to cause right heart failure in adults. A type of ASD called Unroofed Coronary Sinus ASD is observed in 75 percent of the patients with a Left Superior Vena Cava or LSVC that drains into the left atrium. When a cerebral embolism or brain abscess, which is an inflammation with pus caused by matter because of an ear infection, a dental abscess is found, a test for Unroofed Coronary Sinus ASD is generally conducted. Otherwise, the disease is very difficult to detect with no specific symptoms to show.

Details-On-Acute-Coronary-Syndrome      Acute coronary syndrome or ACS is a name given for a set of conditions related to the heart. The diseases included under this are unstable angina and two forms of myocardial infarction. Unstable angina is that which is not related with heart muscle damage. It differs from stable angina in that stable angina occurs during exertion. Stable angina occurs suddenly, even with mild exertion. More..
